 A little NIKE history
 

 1952  Development of an improved Nike missile began to obtain a better performance than MIM-3 Nike Ajax
            (then known simply as Nike).

 1953  The SAM-A-25 Nike B program was formally established. Western Electric was prime contractor, and
            Douglas was responsible for the missile airframe.
 1955  First flight tests with the liquid-fuel sustainer. Very troublesome.
 1956  The Nike B renamed Nike Hercules
 1956  The first successful interception of a drone target occurred
 1957  The new solid-fuel sustainer flew for the first time.
 1958  The first production Nike Hercules missiles were delivered

 The NIKE Area:
 

 IFC (Integrated Fire Control Area) later FCA (Fire Control Area) COMPOSED OF:

    AN ACQUISITION RADAR (ACQ) WITH AN IDENTIFICATION FRIEND OR FOE (IFF) SYSTEM.

    A DIRECTOR STATION (DS)

    A TARGET TRACKING RADAR (TTR)     

    A MISSILE TRACKING RADAR (MTR)

    A TRACKING STATION (TS)
 
   Later they got an HIGH POWER ACQUISITION RADAR (1964) and a TARGET RANGING RADAR (1970)
   This made it possible to engage hostile ballistic missiles.
 
  The distance between the the IFC and the LCA should be 1 to 5 kilometes. Closer than 1 kilometer, the MTR
  was not able to follow the missile du to the launch speed. The IFC nd the LCA were connected by cables.
 

 LAUNCHER CONTROL AREA  (LCA) COMPOSED OF:

   
    MISSILE ASSEMBLY & WARHEAD MISSILE STORAGE FACILIITIES
    A LUANCHER CONTROL STATION (LCS)
    THE LAUNCHERS (3 SECTIONS WITH 3 LAUNCHERS EACH)
    A STORAGE IN EACH SECTION FOR FURTHER MIISILES
    A CONTROL ROOM IN EACH SECTION
    THE MISSILES

  In the launcher area there was an assembly area, where the missiles were  mounted.
  Motor and warhead was mounted in the Revetted Area. 

   

  The distance between the launch sections are long enough, so that the personel could work in open air with
   two sections   while the third was firing.

  The NIKE system worked on normal power (230 V), that was transformed to american values (120 V 400 Hz). 



  The first Danish SAM (surface to air missile) unit, was formed in Fort Bliss, El Paso USA. 1959

  After training they moved back to Denmark. The unit was composed of one staff and four batteries.
  Originally the batteries were part og the Army (10. Luftværnsafdeling) but in 1962 they became part
  of the Airforce as Squadron 531 - 532 - 533 - 534.
 
  The main task was to defend Copenhagen.

 The materiel was mounted 1960, NIKE HERCULES and the older NIKE AJAX. Same year they were
 declared operationel along with the Airforce fighters.

 The Headquartes was in The Avedøre Lejr, a military facility from WW 1, 10 kilometres west of
 Copenhagen 
 The Batteries were mounted in Gunderød (North Sjaelland) Kongelunden on Amager (island on the
 east coast of Copenhagen, Tune 40 kilometrest og Copenhagen and finally Sigeslev 50 kilometres
 south of Copenhagen.

 

 The overall control of the NIKE batteries was the Ejbybro Bunker.
 It was build inthe old fortificaton Line Vestvolden 10 kilometres west of Copenhagen. This facility
 cooperated with the Airforce radar stations and the Airforce command i Karup in Jutland.

  The Missile on the Trolley (USA)

 Repair and assembly of the  missiles, except the motors and the warheads. Also repair of all  the LCA
 equipment.   The trolleys and cranes for the  missiles, that weighted 5 tons each,  were placed at the
 apron  North  of the building . After the assembly,  the missles were brought out of  the southern end
 of the building  and to mounting of the rocket motor and the  warhead in the Revetted Area.

 A little building for storing liquid
 fuel for the NIKE Ajax.

 
 
 A garage for tractors and other
 working vehicles.
 
The Revetted Area. Here rocket motors and warheads were mounted in the missiles.
Outside, but behind the rampage, the NIKE Ajax missiles were fueled with af very flammable mixture of fluid fuel.
 When working with fuel and warheads, the road
 passing  the building was blocked.
 The electronic fence at the road (right) has not
 been confirmed being part of this.

There are no photo of the little store of lubricates and the transformer and Generator house.for tactical power. It contained a transformer to transform Danish power (230 V) to American values
(12o V 400 Hz) The generator could produce tactical power to the area if normal power failed.
The buildings have been use to other purposes and are in a very poor condition.

 


 The Launcher Control Area 



  From the assembly area and the Revetted Area, a road leads about 500 meters to the
 Launcher Area.

         revetted area and the

 Inside the Launch Area, the double fences vith guard towers between the double fense are
 interesting.  These were not  the standards of the Danish military facilities.
 
 
     

The explanation for this high security is, that it might become neccesary to change the normal
 warheads  to  nuclear warheads. This could be done in the Launch Area.
 Denmark had, after heavy Soviet pressure, refused nuclear weapons on Danish soil in mid 50,s.
 But just south of the boarder, nuclear weapons for Denmark was stored. Both for the artillery and the
 missiles.
 In a memo from the chief of defence to the Danish Government april 1959, it is stated, that the few
 number of missiles was not effective unless they were armed with nuclear warheads.
 And here we are talking about all the Danish missiles, both the SAM (Surface to air missile NIKE)  and
 the SSM (Surface-to-surface-missile Honest John)
 
 

 The Launcher Area was composed af 3 launching areas. Each of a storing facility, a
 bunker for the firing crew, 3 launchers and rapages around it.

 the launchers were positioned.

 In the rampage of each of the three launching sections, there was a control bunker.

 1 launcher commander
 1 Panel operator
 3 Missile men ( 1 for each launcher)
 1 Generator operator
 It was possible to slepp inside if high alert was stated. At high alert during the 60´es, they should
 be able to launch the 1. missile within 5 minutes.

 There was contact between the

 In 1969 the NIKE AJAX went out of service and in 1981 and 1983  the 4 NIKE HERCULES Squadrons
 went out of  service.
 For a few years some HAWK batteries were stationed here after The Nike Sections left it.

 543 was the HAWK squadron on the
 HAWK Launch Area Hoejerup untill
 2000.

 
 The NIKE system was replaced by the HAWK in 1981- 83. Hawk was active until 2000.
  

 To day Firing Area Sigerslev is private property. Some of the buildings has been used for different
 activities, and time has been hard for some of them.  


 

The Fire Control Area

At Mandehoved (Flagbanken) the Fire Control Area (the radars) was placed.
There never was a HIPAR at Stevns, only at the base in Tune west of  Copenhagen.

 Today, The Fire Control Area is open for the public. The HIPAR stand is used by ornithologists.

 The barracks was for some years a refuge Center under The Danish red Cross. To day, the
 buildings are empty and for sale.
 

 The Staff

 The Staff of the missile-bataillon was stationed in the Avedøre Camp. Old Barracks from WW 1 in
 Hvidovre,  10 miles west of Copenhagen. The Barracks were build in 1911-13.

 To day, the Barracks is modernized as private flats.
 
 The command building

 

 The Missile Operations Central.

 The command of the missile Defence of  Copenhagen was
 placed at the Ejbybro Bunker just outside the City.
 The area was the pre-WW I defence line of Copenhagen.
 The Bunker consisted of several floors under  the surface.
 The bunker is build into a rampage of the old 1886 defence
 line of the city, and is only visible from the front.

               
         

 Only two corners and the front
 of the bunker  are visible
